The present invention relates to new and useful improvements in printingpresses and has for its primary object to provide, in a manner ashereinafter set forth, a printingpress em- .5bodyinga novelconstruction, combination and arrangement of parts through the medium ofwhich either sheets or a web may be fed to said press.

Other objects of the invention are to provide a press of theaforementioned character which will be comparatively simple inconstruction, strong, durable, highly efiicient and reliable inoperation, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of thefollowingspecificaticn, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:--

Referring now tothe drawings in detail, it will 0 be seen that theembodiment of theinvention which has been illustrated comprises asupporting structure or frame which is designated gen;- erally by thereference numeral 1 and in which the cylinder 2 is operatively mountedin the usual 55 manner. The supporting structure or frame 1 takensubstantially on in section through the FIE of the press includesuprights 3 having mounted on their inner sides pairs of spaced, verticalstrips 4 defining channels 5.

The strips 4 thus constitute guides for the vertically adjustable rackbars 6 which are fixed on the ends of upper and lower rods 7 and 8,respectively, said rack bars 6 having tongues 9 in the form of stripsthereon which are engaged in the/channels Extending transversely betweenthe uprights 3 is ashaft'lo having gears 11 fixed thereon which areengaged with the rack bars 6. Hand wheels 12 are fixed on the ends ofthe shaft 10. Mounted for swinging movement upper rod 7 are arms 13between which theimpressionroller 14 is journaled- The'reference numeral15 designates an elevating rod for. the impression roller 14 which isadjustablyand detachably connected to one of the arms 13, as at 16. Thelower end of the elevating or lifting rod 15 is connected to a bracket17 by a 23.5,

toggle 18. The reference numeral 19 designates a foot plate on thesupporting structure 1 of the press from which a hanger 20 depends.Mounted for rocking movement on the hanger 20 is a spider 21 which isoperatively connected to the toggle 18 by a link 22. Pivotally cc.mounted on the free end portions of oppositely extending legs of thespider 21 are foot pedals 23 which are operable in openings 24 providedtherefor in the plate 19. The

shanks of the pedals 23 are notched, as at 25, for s5,

engagement with the plate 19 for releasably looking said pedals indepressed position. 1 It will'thus be seen that the impression roller 1%may be conveniently swung upwardly away from the cylinder 2 when desiredby simply rocking the spider 21in a direction to elevate the rod 15through the toggle 18. It will further be seen that the supporting meansfor the impression roller 14 may be conveniently adjusted various sizesof cylinders by rotating the shaft 10.

vertically as desired for If desirable or necessa-ry, any suitable meansmay be provided for-retaining the rack bars 6 in vertically adjustedposition The reference numeral 26 designates an inclined, verticallyadjustable feed board having a guide 2'7 thereon. Extending transverselyacross thelower portion of the feed board 26 is a series of openings 28,the purp ently. set forth. I The fe ose of which will be presed board26, is adjustably supported by pairs oflinks 29 which are pivotallyconnected to nuts 30 which are mounted on the oppositely threaded endportions of screw shafts 31 which are coupled to in unison by a chain aneach other for operation d sprocket connection 32.

A hand wheel 33 is provided for raising or lowering the feed board 26.

Journaled in the free end portions of the arms 13 are brackets 34 (seeFigure 5) in which a feeder frame 35 is secured by set screws 36. Itwill thus be seen that the feeder frame 35 is mounted for swingingmovement in a vertical plane on the arms 13. Stop lugs 37 which projectfrom the arms 13 limit the downward swinging movement of the frame 35.

Fixed on the free end of the frame 35 are hearing blocks 33 and 39 inwhich a shaft 40 is journaled, said shaft 40 projecting laterally beyondthe block 38 and having fixed on its projecting end portion a pulley 41.Fixed at spaced points on the shaft 40 are feeding disks or wheels 42.

The bearing block 38 has slidably mounted thereon an elongated housing43 having longitudinal slots 44 therein which accommodate the shaft 40.Journaled longitudinally in the housing 43 is an adjusting screw 45which is threaded through the bearing block 38 and which has fixed onone end a hand wheel 46. Journaled transversely on the lower end portionof the housing 43 is a shaft 47 having pulleys 43 and 49 fixed on itsend portions. pulley as and around a pulley 51 on the upper portion ofthe housing 43, the flights of said belt being engaged withdiametrically opposite sides of the pulley 41 for actuating the shaft40. The pulley 48 rides on a cam 52 which is fixed on the cylinder shaft53, said cam 52 constituting means for driving the feeder and forperiodically raising and lowering the same.

Extending between the bearing blocks 38 and 39 is a bar 54 havingmounted thereon a plurality of stops 55 which are operable in theopenings 28 in the feed board 26. The construction of the feeder is suchthat when. the disks or wheels 42 are raised to inoperative position bythe cam 52 the stops 55 are projected above the upper surface of thefeed board 26 for engagement by the next sheet that is to go into thepress. Of course, when the feed disks or wheels 42 are lowered intoengagement with the'sheet the stops 55 are retracted or lowered topermit the passage of said sheet. This is illustrated to advantage inFigure 7 of the drawmgs.

When the low portion of the cam 52 reaches the pulley 48 the feedingmechanism swings downwardly by gravity for engaging the disks or wheels42 with the sheet, as will be apparent, and when said low portion of thecam passes the pulley 48 the feeding mechanism is raised to inoperativeposition. However, it will be noted that the feeder disks or wheels 42are in constant operation. When the impression roller 14 is swungupwardly or raised the lugs 37 support and raise the feeding mechanism.When a web or roll, instead of sheets, is to be fed into the press, thefeeding mechanism is simply swung upwardly and forwardly to an out ofthe way position on the An endless belt 50 is trained around the i 2.
